FIG. 1 is a block diagram of a Social Networking System (SNS) for providing a map service according to an exemplary embodiment of the present invention.

Referring to FIG. 1, the SNS includes a service provider 100 and a service user 200.

The service provider 100 may include a server for performing wired/wireless network communication and may provide a map service to the service user 200 that subscribes to an SNS.

The service provider 100 may store information about at least one of user importance of the service user 200, a propagation range being a maker display range in the map service, and the importance of information represented by markers.

The service provider 100 may store the user class of the service user 200 as the user importance of the service user 200 and may update the user class in real time according to at least one of the number of service uses, acquired points, the participation of the service user 200 in events held in the SNS, and the importance of information provided by the service user 200.

The propagation range refers to the display range of markers representing information in the map service according to the user importance of the service user 200. The service provider 100 may set the propagation range according to the user importance. If the user importance is updated in real time, the service provider 100 may also set the propagation range in real time.

The importance of information represented by a marker refers to a weight applied to the information in the map service. The service provider 100 may or may not display markers, or may display markers differentially, according to the importance of information represented by the markers.

The service provider 100 may update the importance of information in real time according to at least one of the user class of a user that has provided the information, responsiveness to the information such as the number of replies to the information, the number of views for the information, the number of recommendations that the information has received, a last update date of the information, and an expiration time of the information. In addition, the service provider 100 may display markers differentially in at least one of size, color, shape, and transparency and may change a displayed propagation range, according to the real-time importance of information represented by the markers.

The service provider 100 may store, as personal information of the service user 200, basic information of the service user 200 such as at least one of an IDentifier (ID), a name, an age, a gender, etc. of the service user 210 and details of the service user 200 such as at least one of an education level, tastes, hobbies, etc.

When the service user 200 connects to the service provider 100 and requests the map service, the service provider 100 may differentially display information corresponding to tastes and interests of the service user 200 included in the stored personal information by means of markers.

The service provider 100 may display a plurality of markers representing a plurality of pieces of information to the service user 200, differentially in at least one of size, color, shape, and transparency according to the importance of the information or the tastes and interests of the service user 200.

The service user 200 may make a decision as to how markers are to be displayed differentially or change existing differentially displayed markers in terms of at least one of size, color, shape, and transparency.

The service provider 100 may display markers of the same importance differentially according to the distances between the service user 200 and the markers.

The service provider 100 may display markers differentially in at least one of size, shape, color, and transparency according to a change in the distances between the service user 200 and the markers in a propagation range set based on the user importance of the service user 200 or the importance of information represented by the markers.

If a plurality of neighboring markers are displayed overlapped in the map service, the service provider 100 may display the markers differentially in at least one of size, shape, color and transparency according to the importance of information represented by the markers.

If display of information is set as restricted by an information provider, the service provider 100 may restrict the display of a marker representing the information in the map service even though the information falls into the propagation range.

The service provider 100 may display markers in a propagation range set manually by the service user 200. The manually set propagation range should be within a propagation range set according to the user importance of the service user 200.

The service provider 100 may provide the service user 200 with information about an event or activity that will increase the user importance of the service user 200 in the SNS.

When a map is scaled down and thus a plurality of markers are overlapped on the map in the map service, the service provider 100 may determine the importance of information represented by the markers and display only a marker representing information with a highest priority level based on the importance of the information.

With the marker representing the information with the highest priority level displayed in the map service, the service provider 100 may indicate the existence of markers that represent information with lower priority levels and thus are not displayed. For example, the number of non-displayed markers representing information with lower priority levels may be displayed in the vicinity of the marker representing the information with the highest priority level. Alternatively, when the marker representing the information with the highest priority level is touched, the number of non-displayed markers with lower priority levels may be displayed. Alternatively, when the marker representing the information with the highest priority level is touched, the non-displayed markers with lower priority levels may be displayed for a predetermined time adjacent or otherwise near the marker representing the information with the highest priority level.

Alternatively, with the marker representing the information with the highest priority level displayed in the map service, the service provider 100 may display markers with lower priority levels transparently. Herein, the transparency of the markers with lower priority levels may be different according to the priority levels of the respective markers.

Alternatively, with the marker representing the information with the highest priority level displayed in the map service, the service provider 100 may display the markers with lower priority levels differentially from the marker representing the information with the highest priority level.

When the displayed marker representing the information with the highest priority level is touched, the service provider 100 may display an information list of the markers that represents information with lower priority levels and thus are not displayed.

Each time the displayed marker representing the information with the highest priority level is touched, the service provider 100 may display the non-displayed markers with lower priority levels in a predetermined order.

While the marker representing the information with the highest priority level is being displayed, the service provider 100 may deactivate the markers that represent information with lower priority levels and thus are displayed transparently or in a different shape from the marker representing the information with the highest priority level.

The service user 200 may be a portable terminal of a user that has subscribed to the SNS including the map service and thus receives the map service.

According to exemplary embodiments of the present invention, the portable terminal may be any of a Global System for Mobile communication (GSM) terminal, a Universal Mobile Telecommunication Service (UMTS) terminal, a Code Division Multiple Access (CDMA) terminal, a Wideband Code Division Multiple Access (WCDMA) terminal, an International Mobile Telecommunication 2000 (IMT-2000) terminal, a General Packet Radio Service (GPRS) terminal, etc. Accordingly, the portable terminal may include a display for displaying information to a user, a processor for controlling the portable terminal and controlling the portable terminal to perform any of the functions described herein, an input unit for receiving input from the user, a memory for storing data, a transceiver for transmitting and/or receiving data, etc.

Upon request of the service provider 100, the service user 200 transmits personal information to the service provider 100. The personal information may include basic information such as at least one of a name, a gender, a height, an age, a nickname for conversation, etc. and personal details such as at least one of an education level, tastes, preferences, interests, etc.

The service user 200 may access the service provider 100 and request the map service to the service provider 100, so as to display a plurality of markers representing information differentially according to the user importance of the service user 200 or the importance of the information, or according to the user importance, tastes, and interests of the service user 200 in the map service.

An operation for displaying markers in the map service in the social networking system will be described in more detail with reference to FIGS. 2 to 4G.

FIG. 2 is a flowchart illustrating an operation for displaying markers according to their respective importance in a map service according to an exemplary embodiment of the present invention.

Exemplary embodiments of the present invention will be described with reference to FIGS. 1 and 2.

Referring to FIG. 2, upon request of the service user 200 connected to the service provider 100 for the map service in step 201, the service provider 100 determines the user importance of the service user 200 in step 202.

More specifically, the service provider 100 determines the stored user class of the service user 200 to thereby determine the user importance of the service user 200 in step 202.

The user importance represents the user class of the service user 200 in a subscribed service. The user class involves at last one of the number of service uses, acquired points, the participation of events held in the service, and the importance of information provided by the service user 200.

In step 203, the service provider 100 determines a propagation range according to the user importance, that is, the user class of the service user 200.

For instance, if propagation levels 1 to 15 are defined and user classes are defined as beginner, intermediate, and premium, the service provider 100 may set a propagation range spanning from level 1 to level 5 for a beginner member, a propagation range spanning from level 6 to level 10 for an intermediate member, and a propagation range spanning from level 11 to level 15 for a premium member.

Once the propagation range is set according to the user importance of the service user 200, the service provider 100 determines the importance of information within the propagation range in step 204.

The importance of information involves at least one of the user class of an information provider in the subscribed service, responsiveness to the information, a last update date of the information, and an expiration time of the information.

More specifically, the service provider 100 determines the importance of information within the propagation range and extracts information with a predetermined importance level or higher. For example, if information importance levels are defined as high, medium, and low, the service provider 100 may extract only information at the high or medium level.

Alternatively or additionally, the service provider 100 may extract information at an importance level corresponding to the user importance of the service user 100. For instance, if the user class is intermediate or higher, the service provider 100 may extract only information at the medium or high importance level.

Herein, the service provider 100 may exclude information set as display-restricted from the information that falls into the propagation range.

Then, the service provider 100 provides to the service user 200 with a map service that displays markers representing the extracted information according to the user importance, the information importance, and the propagation range in step 205.

More specifically, the service provider 100 provides the service user 200 with a map service that displays the markers differentially in at least one of shape, size, color, and transparency according to the importance of the information represented by the markers. Thus, the service user 200 may display the markers differentially according to the importance in the map service.

Alternatively, the service provider 100 may provide the service user with a map service that displays the markers differentially in at least one of shape, size, color, and transparency according to the tastes and interests of the service user 200 stored as personal information as well as the importance of the information represented by the markers.

In addition, the service provider 100 may provide the service user 200 with a map service that displays markers of the same importance differentially according to the distances between the service user 200 and the markers.

Alternatively, the service provider 100 may display information corresponding to personal tastes and interests by means of markers, upon request of the service user 200.

It may be further contemplated that the service provider 100 reads information about the tastes and interests stored as the personal information of the service user 200 and extracts only information matching the tastes and interests within the propagation range, instead of the information importance in step 204 and provides the service user 200 with a map service in which markers representing the extracted information are displayed according to the user importance, the tastes and interests, and the propagation range in step 205.

Herein, the service provider 100 may provide the service user 200 with a map service in which the markers can be displayed differentially in at least one of shape, size, color, and transparency according to the user importance and the personal tastes and interests.

While the map service is being provided to the service user 200, upon detection of a change in the user importance and/or the information importance in step 206, the service provider 100 may provide the service user 200 with the map service in such a manner that changed markers are displayed according to the changed importance and propagation range in step 207.

The user importance of the service user 200 is the user class of the service user 200. When at least one of the number of service uses, acquired points, participation in events held in the service, and the importance of information provided by the service user 200 is changed, the service provider 100 updates the user importance in real time according to the change.

When at least one of the user class of an information provider that has provided information in the service subscribed by the service user 200, responsiveness to the information, a last update date of the information, and an expiration time of the information is changed, the service provider 100 updates the importance of the information in real time according to the change.

In this manner, the service provider 100 can provide the service user with the map service in real time, in which markers representing information are displayed by reflecting a change in the user importance and/or the information importance in real time.

FIGS. 4A to 4G are views referred to for describing display of markers in a map service according to exemplary embodiments of the present invention.

FIG. 4A illustrates markers displayed in different sizes according to the importance of information represented by the markers according to an exemplary embodiment of the present invention. In many other ways, the markers may be displayed differentially in a map service according to the information importance, as stated above.

FIG. 4B illustrates markers that the service user 200 displays in different sizes according to information importance in a map service provided by the service provider 100 according to an exemplary embodiment of the present invention.

FIG. 4C illustrates a marker that the service user displays in different sizes in real time according to changed distances between the service user 200 and the marker in a set propagation range in a map service provided by the service provider 100 according to an exemplary embodiment of the present invention.

Referring to FIG. 4C, when the service user 200 moves from a position A in (a) of FIG. 4C to a position B in (b) of FIG. 4C, approaching the position of the marker, the marker may be displayed larger than when the service user 200 is located at the position A.

FIG. 4D illustrates overlapped markers at nearby positions that the service user 200 displays to different transparency degrees according to the importance of information represented by the markers in a map service provided by the service provider 100 according to an exemplary embodiment of the present invention.

FIGS. 4E and 4F illustrate markers that the service user 200 displays in real time, when information about the markers is changed according to responsiveness of information such as at least one of a user class, the number of replies, the number of views, the number of recommendations, a last update date of the information, and an expiration time of the information in the map service provided by the service provider 100 according to exemplary embodiments of the present invention.

Referring to FIG, 4E, information represented by a marker A gets more important, for example, due to an increase in the number of views for the information in (a) of FIG. 4E. Thus, the marker A is displayed larger in (b) of FIG. 4E. On the other hand, information represented by a marker B gets less important, for example, due to a decrease in the number of views for the information in (a) of FIG. 4E. Thus, the marker B is displayed smaller in (b) of FIG. 4E.

Referring to FIG. 4F, in (a) of FIG. 4F, information represented by a marker A gets more important, for example, due to an increase in the number of views for the information. Thus, the marker A is displayed larger and a propagation range in which the marker A can be displayed is also widened in (b) of FIG. 4F. The widened propagation range in (b) of FIG. 4F includes service user 200.

FIG. 3 is a flowchart illustrating an operation for displaying overlapped markers according to their respective importance in a map service of a portable terminal according to an exemplary embodiment of the present invention.

Exemplary embodiments of the present invention will be described below with reference to FIGS. 1 and 3.

Referring to FIG. 3, while the service user 200 is displaying a plurality of markers in a map service provided by the service provider 100 in step 301, when a map is scaled down and thus the markers are overlapped in step 302, the service provider 100 determines the importance of information represented by the overlapped markers in step 303.

The service provider 100 provides the map service to the service user 200 in such a manner that only a marker representing information with a highest priority level is displayed according to the determined information importance in step 304.

In addition, the service provider 100 may indicate the existence of markers that represent information with lower priority levels and thus are not displayed by a number, display the markers that represent information with lower priority levels around the marker representing the information with the highest priority level for a predetermined time, or display the markers that represent information with lower priority levels to different transparency degrees according to their priority levels.

In addition, the service provider 100 may display the markers that represent information with lower priority levels differentially from the marker representing the information with the highest priority level in at least one of shape, size, and color.

While the marker representing the information with the highest priority level is being displayed, the service provider 100 may deactivate the markers that represent information with lower priority levels and thus are displayed transparently or differentially from the marker representing the information with the highest priority level.

When the displayed marker representing the information with the highest priority level is touched in step 305, the service provider 100 may provide the service user 200 with an information list of the markers that represent information with lower priority levels and thus are not displayed, so that the service user 200 can display the information list in the map service in step 306.

Each time the displayed marker representing the information with the highest priority level is touched, the service provider 100 may provide the service user 200 with the map service in such a manner that the non-displayed markers with lower priority levels can be displayed in a predetermined order.

FIG. 4G illustrates markers displayed by the service user 200 in a map service provided by the service provider 100 according to an exemplary embodiment of the present invention. Referring to FIG. 4G, in the map service, when a map is scaled down and thus a plurality of markers are displayed overlapped, only a marker representing information with a highest priority level is displayed according to information importance, while the other markers are displayed to different transparency degrees in different sizes according to the priority levels of information represented by the markers.

As is apparent from the above description of the method for displaying markers in a map service according to exemplary embodiments of the present invention, a plurality of markers are displayed differentially according to the importance of information represented by the markers in the map service. In addition, when a map is scaled down and markers are displayed overlapped, only a marker with a highest priority level is displayed. In this manner, markers representing information can be displayed effectively.

At this point it should be noted that the exemplary embodiments of the present disclosure as described above typically involve the processing of input data and the generation of output data to some extent. This input data processing and output data generation may be implemented in hardware or software in combination with hardware. For example, specific electronic components may be employed in a mobile device or similar or related circuitry for implementing the functions associated with the exemplary embodiments of the present invention as described above. Alternatively, one or more processors operating in accordance with stored instructions may implement the functions associated with the exemplary embodiments of the present invention as described above. If such is the case, it is within the scope of the present disclosure that such instructions may be stored on one or more non-transitory processor readable mediums.
